HP 42S, DM 42 Integral

[lrdheat]

On my 42S, the integral of SIN X from 0 to 2pi produces 3.674E-12 (very close to the actual answer of 0, using an accuracy of 1E-5) nearly immediately.

My DM 42 takes a long enough time where I give up. Same 1E-5 accuracy, even tried different accuracies ranging from .1 to 1E-12 on the DM 42.

My code is lbl “fx”
MVAR X
RCL X
SIN X
END

Both the 42S and DM 42 very quickly come up with 2.000

Any idea as to why the DM 42 has trouble with the domain of (0,2pi) ?
